CLOCK GONG AND BELL.

SPECIFICATION forming part of Letters Patent No. 334,012, dated January12, 1886.

Application filed October 9, 1884. Renewed December 5, 1885. Serial No.184,804. (No model.)

To all whom it may concern:

Be it known that I, GEORGE GARDNER, a citizen of the United States,residing at Winsted, in the county of Litchfield and State ofConnecticut, have invented new and useful Improvements in Clock Gongsand Bells, of which the following is a. specification.

My invention relates to a gong 0r bell for clocks,upon which the hoursmay be indicated or alarms may be struck by means of a hammer in theusual or any desired manner.

My invention consists in a novel construction of a series ofsounding-plates and the coiled spring, gong, or hell, and thecombination and arrangement thereof with relation to each other, wherebythe vibrations are increased aud multiplied and rendered more distinctthan heretofore, and the sound is-intensified and improved, ashereinafter more particularly described.

In the accompanying drawings, Figure 1 represents a perspective view ofthe invention; and Fig. 2, a central vertical section of the same, takenon line 2 2, Fig. 1.

A represents a plate, preferably metallic and circular in shape, havingconnected with it, by a post, a, near its upper edge and in front of it,two smaller plates, B and C,wh ich I also prefer to construct of metaland of circular shape. The plate A, post a, and the plates B and C maybe formed in one piece, or may be constructed separately and fastenedtogether in any well-known manner.

At a point about diametrically opposite the post a, or near their loweredges, the plates B and C are connected to each other by a bolt, E,passing through a washer or roller, D. To this washer or roller issecured the lower end of a steel spring, G, which is formed into a coil,which I prefer to construct extending upward above the upper edges ofthe plates, with the post a insideof the coil. The coil thus formedconstitutes the gong. In operation, after the parts are assembled, theplate A is attached to the back of the clock on the inside of the caseby screws passed through the plate A and into the clock-back in properposition relative to the striking mechanism of the clock, which isconstructed in any usual or preferred manner.

As the hammer strikes the coil G the vibrations are conveyed to theplates 13 and C, which vibrate in unison therewith, and thence they areconveyed by means of post a to the plate A, which acts as asounding-board, and the vibrations are thus multiplied, and the volumeof sound is increased and rendered more sonorous and musical. As thepost a conveys the sound very rapidly to the plate A, I have found inpractice that no matter how rapidly the hammer may strike the gong thereis no running together of the sound, but each vibration is separate anddistinct. The best results are attained when the striking part of thehammer is made of leather.

When constructed as hereinbefore described, my sounding device is veryp0werful,while at the same time the sound is very sweet, soft, andprolonged.

A bell may be used in place of the gong with satisfactory results. Iprefer, however, to use the gong, as hereinbefore described.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is

1. An attachment for a clock gong or bell, consisting of a series ofparallel disks or plates connected together by a transverse post or bar,connecting the series so as to hold them relatively secured togetherwith small spaces between them, and two of the said sounding plates ordisks further attached together by an intervening bolt or pin, to whichis attached the sounding device, substantially as shown and described. IY

2. The combination of the plate A, post a, plates B C and gong G, andmeans for securing the same in place, substantially as shown GEORGEGARDNER.
